Just finished a 2008 league and had 2 unusual stats given the lack of usage:
My closer, Grant Balfour, posted a 20 win/20 save season. From what I could find, only 6 players have ever accomplished this in MLB over the course of their career, let alone in the same season. (I realize 128 IP is a lot of usage for a closer, but he still had more wins than my #2 starter with 321 IP.)
My DH vs. RHP, Russell Branyan, hit 53 HR in only 386 AB. Second-most HR in the league despite being well below the AB/PA minimum to qualify.
